Abstract: A single port pump impeller (20) includes two pump vanes (30) diverging arcuately and radially from a suction eye (40) to form one open expanding chamber (50), and includes a blocking wall (56) for closing t he remaining, opposite expanding chamber. The two vanes are contained within parallel spaced apart shrouds (24, 26). The shrouds include increased wall thickness regions to dynamically balance the impeller. The blocking wall can include a small aperture (86) for providing a small stream of liquid to flow into the otherwise closed expanding chamber to prevent cavitation at a distal end of an adjacent vane. Alternately, the otherwise blocked expanding chamber can be filled with a solid material having substantially the same weight as the flu id being pumped, e.g., water, to prevent cavitation at the outside edge of one of the adjacent vanes.

Abstract: L'invention concerne un procédé et un système servant à déterminer la constitution d'une boucle d'abonné (220). Le procédé consiste à envoyer des impulsions vers une boucle et à obtenir des données en fonction des signaux reçus en écho, à déterminer (7301) chaque discontinuité de la boucle à partir de ces échos reçus, et à déterminer, sur la base de chaque discontinuité, une fonction de transfert de canal (7305) pour chaque section de boucle précédant la discontinuité. La fonction de transfert est alors utilisée pour synthétiser un filtre inverse (7309), et ce filtre inverse et les données obtenues sont convolutionnées pour toutes les sections de boucle précédant la discontinuité (7313). On peut encore améliorer ce procédé en modélisant des échos parasites et en soustrayant ces échos aux échos produits dans la boucle.

Title: Image-forming machine having charger cleaning activation after an arcing fault and related method
Inventor: REGELSBERGER MATTHIAS H
IPC: H01T19/00
Filed: 2001-07-06
Granted: 2005-09-20
Abstract: The present invention provides an electrophotographic (EP) image-forming machine and related method having activation of a charger cleaner in a corona charger after an arcing fault. The corona charger has corona wires connected to a high voltage potential supply, preferably providing a voltage in the range of about 5 to 11 kva or in the range of about 13,000 to 22,000 volts peak-to-peak. A corona voltage detection circuit is connected to measure current changes in the high voltage potential supply. A grid has a preselected electric potential to control the charge. The grid may be grounded, but preferably is connected to a power supply providing a voltage in the range of about 300 to 900 volts. A grid voltage detection circuit is connected to measure current changes in the power supply. The voltage detection circuits provide a voltage signal to a microprocessor. When arcing occurs, the microprocessor cycles the EP image-forming machine into a standby mode.     The charger cleaning apparatus is activated to clean the charger. When the cleaning is completed, the EP image-forming machine returns to normal operation. In a further aspect of the present invention, the image-forming process stops when arcing occurs. The charger is cleaned. Any prints affected by the arcing are disposed. The image-forming process restarts at the image frame where the arc occurred.

Abstract: Méthode permettant de traiter le cancer, fondée sur l'ultraphérèse, perfectionnée pour prélever des composés d'un poids moléculaire inférieur à 120.000 daltons, puis sur l'administration de fluide de remplacement pour stimuler le système immunitaire du patient afin qu'il attaque les tumeurs solides. Dans le mode de réalisation préféré, le patient subit une ultraphérèse à l'aide d'un ultrafiltre à tubes capillaires dont la taille des pores va de 0,02 à 0,05 microns et dont la limite du poids moléculaire est de 120.000 daltons, suffisant pour filtrer un volume de sang. Le fluide de remplacement préféré est du plasma normal obtenu par ultraphérèse. Le patient est de préférence traité quotidiennement pendant trois semaines et des examens diagnostiques sont effectués pour vérifier qu'il y a eu régression tumorale, puis ce schéma de traitement est répété. Ce traitement est combiné de préférence avec une autre thérapie, par exemple le traitement à l'aide d'un composé anti-angiogène, d'une ou plusieurs cytokines telles que le TNF, l'interféron gamma ou IL-2, ou d'un composé favorisant la coagulation. Le traitement augmente les taux endogènes locaux de cytokines telles que le TNF, ce qui constitue une base pour un effet accru lorsque ce traitement est combiné avec tout autre traitement qui favorise l'activité des cytokines contre les tumeurs, par exemple les traitements à base d'agents d'alkylation, de doxyrubicine, de carboplatine, de cisplatine et de taxol. Alternativement, le traitement par ultraphérèse peut être combiné avec une chimiothérapie locale, une chimiothérapie systémique et/ou une radiothérapie.

Abstract: An inquired destination A determines an argument .alpha. every time an inquiry received, cuts out part of stored electronic information C a, measures its attribute, and forms a information C a, measures its attribute, and forms characteristic information I A, for transmission to an inquiring source B along with the argument .alpha.; while the inquiring source cuts out the same part, as cut out by the inquired destination, of electronic information C b stored by itself by applying the augment .alpha., forms characteristic information I B in the same way as done by the inquired destination, and checks it against the characteristic information I A received from the identity between the two elements of electronic information C a, C b. Therefore, the above method can provide a high-reliability checking result by transmitting a very small amount of information without transmitting the contents of the electronic information at all.
